Navigate to the Releases page.

• Download Windows build

You need the following software, to build OpenHantek from source:

• CMake 3.5
• Qt 5.4
• FFTW 3 (prebuild files will be downloaded on windows)
• libusb 1.x (prebuild files will be used on windows)
• A compiler that supports C 11

We have build instructions available for Linux, Apple MacOSX and Microsoft Windows.

You need an OpenGL 3.2 or OpenGL ES 2.0 capable graphics hardware for OpenHantek. OpenGL is prefered, if available. Overwrite this behaviour by starting OpenHantek from the command line like this: OpenHantek --useGLES.

USB access for the device is required:

• As seen on the Microsoft Windows build instructions page, you need a special driver for Windows systems.
• On Linux, you need to copy the file firmware/60-hantek.rules to /lib/udev/rules.d/ and replug your device.

Please refer to the Specifications, Features, Limitations page.

We welcome any reported Github Issue if you have a problem with this software. Send us a pull request for enhancements and fixes. Some random notes:

• Read how to properly contribute to open source projects on GitHub.
• Create a separate branch other than master for your changes. It is not possible to directly commit to master on this repository.
• Write good commit messages.
• Use the same coding style and spacing (install clang-format. Use make target: make format or execute directly from the openhantek directory: clang-format -style=file src/*).
• Open a pull request with a clear title and description.
• Read Add a new device if you want to know how to add a device.
• We recommend QtCreator as IDE on all platforms. It comes with CMake support, a decent compiler, and Qt out of the box.
